Been hearing about this on and off for a few years, but it seems things have come to a head with the airing of a four-part documentary series about the massive scandal of the “Horizon” financial software used by the British Post Office <https://www.aljazeera.com/news/2024/1/9/the-great-british-post-office-scandal-explained>. Basically, the buggy software was reporting incorrect transaction amounts, and these reports were believed over the protestations of the branch managers, leading to several hundred of the latter being prosecuted and convicted of theft and false accounting. In desperation at not being believed, some of them tried to plug the holes with their own money. Some even committed suicide. It took twenty years from the introduction of the system before a court ruled that the fault lay with the software, not with so many innocent people. (Why was the software considered to be above reproach for so long?) Even now, only a small proportion of the false convictions have been overturned. The Post Office CEO at the time has bowed to pressure and returned her CBE award. The software is still in use.
